Unclean class loader on shutdown
I'm seeing the following error during shutdown of the server:

The tomcat connector lifecycle is out of synch with the server class loader, which has already been unregistered with he deployment repository.
Related to other posts about updating tomcat integration in jbossas5, we need to have proper dependencies of all the beans making up the web container so this type of lifecycle problem is handled automatically.
